MONOLlNE-MACHINE Specification of Letters Patent.

Application filed March 5', 1907. Serial No. 360,798.

which are commonly known under the trade mark Monoline" .and represented as to their general organization-in Letters Patent of' the l'nited States No. 506,198, and also in more il'nproved form in application for Letters Patent oi the UnitedStates filed-by me on the 14th day of July, 1905, Serial No. 209,74s.

In this class of machines, the matrices, each containing several characters in the vertical edge, are dropped one after another into a ct-miposing box in which they are individually arrested at different levels, to bring the selected characters to the alining level, and thereafter delivered laterally from said box to the end of the line'which is being composed, the matrices in the composed line. being retained individually at the proper heights by a horizontal assemblingrail or bar, which enters notches in their edges. As the composed line increases in length, it is advanced against a. yielding resistant While the successive matrices at the. rear end are carried past and retained by spring pawls or dogs.

In thecourseof compositionit is frequently desirable to remove the last matrix from the line either because the linh iseomposed to an excessive length 'or because an undesirable character has been accidentally set in the. line. I

I n the machine as originally constructed,

-the detaining devices which held the matrices at tl to rear end of the line were of such form and were housed in or covered in such manner that the removal of a matrix was attended with much trouble and loss of time.

The object of the. present inventionis to overconu this dillieulty and provide for the instantaneous release of the last matrix so that it may be speedily removed. and to this end it consists broadly in combining with. the matrix-retainingdevices means whereby they may be disengaged and held for the time bcingput of action.

In the accompanying drawings I have shown my improvementin-the formadapted for use in the machine represented in my aim plieation Serial No. 269,748, before referrer to, and with the 'exception of'the parts specifically described herein, the machine may Patented une 11,1967. 7

be in all respects identical with that described in said application, but it is to be understood that the details may be variously modified without changing. the mode of action or passing beyond the limits of my invention. i

In the drawings,Figure 1 is a front elevation of the composing-box and -adjacent parts with any improvement incorporated therein. Fig. 2 is a side eleva-tion'of the same looking from the left. I Fig; 3-is a horizontal section on the line 38 of the prc' ceding figures, with the parts in the. normal or operative positions; Fig. 4- is a similar view with the parts adjusted to release the last matrix.

Fig. 5 1s a plan view on an enlargedscale, of parts shown in the preceding figure.

Referring to the drawings, 1, 1, represent the matrices each consisting of'an elongated bar having a suspending hook at the upper end, a series of lntaglio characters or mat riees in one vertical edge, and a correspondmg series of alining notches in the opposite edge. 'lhese matrices, bearing different groups of characters, are stored in a magazinc and delivered one at a time therefrom through intermediate mechanism by finger keys representing-the various characters and spaces. The matrices are delivered downward in an cndwisc direct-ion behind a glass door or guide 12", into the. assemblin box 4, beside an upright front-plate 32. '1 my are arrested at different-heights by stopdevices controlled by the respective finger-keys.

Each matrix, after bei v arrested with the designated character at t 10 alining level, is.

maintainedtemporarily by a horizontally swinging bridge-plate 29, which enters one of the notches inthc rear ed e ofthc matrix, as shown in Fig. 2. engagement with the matrix, forms a continuation of the horizontal fixed assemblin rail ZS'upon which the matrices are pushc' one alter another by the-action of the'reciprocating pusher 2t}, the-plate :52 being autos malicall y withdrawn in a rearward direction before the pusher advances.

'This fridge, when in dogs or pawls turning. on vertical pivots an The advancing line acts against and is held in compact order by the horizontally yielding resistant 49. As the successive matrices are added to the rear end of the line, the line is advanced bodily along the line-race and 'rail 28, and retained by spring-actuated detents .40. These detents are shown in the form of the matrix 1 may be turned from its normal position, shown in Fig. 3, backward away from the line, as shown 'n Figs. 4 and 5, after which it may be lifted o t of the machine.

It will be observed that when the matrix is thus turned horizontally away from the line in the course of its removal, it leaves the remaining matrices in e agement with the rail 28, so that there is noanger of their falling out of position or below their proper heights.

Instead of constructing the matrix-sup porting bridge 29 as heretofore, I now provide it at one end with a lip or projection29", adapted to e age the end of the matrixdetent 40, so t rat when the bridge is swung backward from the operative position, shown in Fig. 3, to the sitlon shown in Figs. 4 and 5., beyond the iiiild of the descending matrices, it will act upon the end of the detent 40 and throw the latter back out of engagement with the matrix line. With the parts in this position, the operator may readily gras the'last matrix and turn it awa from the inc and out of engagement with t e rear detent 40, as shown in Figs. 4 and 5, after which the matrix may be withdrawn from the machine, the whole operation being practically instantaneous.

For the 'pur ose of throwing the bridge backward and olding it in fposition to kee the front detent 40 out o engagement, pivot to the frame the lever 29 arranged to act at one end against the bridge 29; This lever stands normally in the position shown in Fig. 3, ermitting the bridge to operate substantial y as in the original machine. Whon, however, the lever is turned to the position shown in Figs. 4 and 5, it causes the brid e and the detent 40 to swing backward and ocks them in position. Thls action is due to the fact that the coacting ends of the bridge 29 and'lcver 29 are eccentric to their .arrange the lever in the path 0 .under the rear end of this pivots, and so formed that when the lever be:

gins its movement, its extremity will first cause the bridge to swing backward or outward around its pivot until it assumes the position shown in Figs. 4 and 5, after which the continued movement of the lever causes its end to abut against the extremity of the bridge, as shown, so as to hold the same in position. A

In order to permit the removal of the ma trix at any time, it is necessary to insure the withdrawal of the front-plate 32 before thedetent 40 is disengaged. In order to effect this action automaticallv, I provide the glass door or guide 12 at the lower end with a projection 12 'to act against a sliding plate 12 mounted on the frame. This plate, whi'ch,is slotted and guided by screws 12, is so formed that it will enga e at the rear end with the slidinghrod 33, which carries the front-plate 32, as eretofore.

When the door is closed and the parts are in normal position, the late 32 is free to move automaticallyforwar andbackward asusual,

but when the door 12 is opened to give access to the internal parts, the projection 12 pushes the plate 12 backward and causes the withdrawal of the plate 32, thus leavin an unob structed space throu h which the matrix may be removed. W on the door is closed, the parts automatically resume their positions.

While I have described my invention in that form which I consider best adapted for useiin the monoline machine, it is to be understood that the form and arrangement of the arts may be modified to an extent within t e range of mechanical s ill, provided they have a mode of action substantially such as stated. I

I believemyselt to be the first to combine with detents to retain the matrices added to a line in course of composition, means of any iergty removed. .v

ile I have shown my invention in a monoline machine, it is obvious that it may be used in any analogous machine in which a composing mechanism delivers matrices suc cessively to retaining devices or detents at the end of the line. I The lever 29 may be restored by hand to its normal inactive position, but in-order to save'time and relieve the operator I refer to i: t e usual horizontally vibrating yoke 37, employed to return the sto s, asheretofore.

The glass p ate or door 12 which swings horizontally is held normall in the closed position by an overlying late 12 pivoted to the frame to swing vertically. A spring 12 atch presses its R ngling der of this latch bearing against the door is ward end downward over the front edge of the (10111. It is to be observed that the shoulinclined or beveled. "This is for the purpose 5 tion of notched matrices, a movable bridge to temporarily sustain the. matrices as they are of permitting the door to swing open automatieally whenever pressure is exerted against its inner face by descending matrices or spacers which are lodged against one another or which are otherwise thrown out of position.

The holding of'the door in such manner that it will swing open under moderate pressure is a new feature in this class ofmachines, and itis to be understood that the catch may be modified in form at will rovided only that it is adapted to release the door under the conditions stated.

Having described my invention, what I claim and desire to secure by Letters Patent is:

1. In a monoline machine, matrices each containing a series of characters and alining notches, means for delivering the matrices successively to a common line of one height or another, as demanded, means for sustaining the matrices at the proper height, a yielding detent to engage and hold the successive .niatrices as they. areadded horizontally to the line, and a manual device for operating the detent at will to disengage it from the last matrixywhereby the ready; removal of the matrices by a turning and lifting movement may be effected.

2. In a matrix composing machine, means for assembling the matrices horizontally In line, means for maintaining the individual matrices at one hci ht or another in the line, as demanded, yielding detents to hold the successive matrices as they are added to the line, and means for throwing one of said detents out of action independently ofthe other at-will.

3. In a composingmechanism, a. yielding detent to engage the successive matrices as they are added to the line, and mechanism for disengaging the detent at will and looking it out of action.

4. In a inoholine machine, the combinaadvancing toward the line, a detent to retain the matrices at the end of the line, the bridge being arranged to throw the detent out of ac tion.

5. In a monoline machine, the combination of notched matrices, the fixed rail 28, swinging bridge 29, and the yielding detent 40, arranged to be thrown out of action by the bridge.

6. In a monoline machine, and in combiner tion with the notched matrices, means for as;

semblin the same in line, a detent to engage and 11015 the last matrix in the line, a reciproeating front-plate 3:2, and means for moving the front-plate and the detent away from their operative positions to release the end matrix; whereby the ready removal of said matrix from the machine is permitted.

7. In amonoline machine, and in combination with the reciprocating front-plate 32,

the swinging door 12, and intermediate devices actuated by the door to cause' the retreat of the plate.

S. In a monoline machine, and'in combination with the reciprocating frontlate 32, the door 12", and the intermediates 1de'12.

9. In a monoline machine, and in combination with the detent 40, the bridge 29 acting thereon, and the lever 29 arranged to move and lock the bridge.
